METALLIC- s'riwc'runn.

To all'whom it may concern.

- Be it known that I, lVlAtmIcn LAOHMAN, a citizen of the United States,and a resident of New York, in the county .of'Ncw York and State of NewYork,'have' invented a certain new and useful Metallic Structure,

'of which the following is a specification.

*My invention relates to metallic structures or fabrics such as used forreinforcement I poses and jao for concrete work, lathin and otherpurcomprising memdmrs crossing one another and secured together at theirintersections by suitable fastenin 's.

The invention is particu arly useful in connection with metallicstructures. or fabrics whichare to be used for reinforcement forconcrete work, such as for joining sections of metallic fabric togetheror for fastening the members of the fabric or structure at their pointsof intersection.-

One of the objects of the invention is to operation can be quickly .andsecurely done by the workmen atthe place it is desired to usethe fabric.a r i Another object is to provide the members of a metallic structurewith means-whereby they can be readily and quickly secured together,thesemeans being permanently located on one ofthe members "whendetached, whereby they can be shipped in bundles andcan be'quicklysecured-attheir intersecting points when desiredto form the fabricOIjStIllCtUlG and proper'spacing attained.

A s'till further object is to provide a bar or wire with clips welded toit at intervals apart'by means of which the bar or wire may be securedto a companion member. whereby reinforcements for use in any shaped formmay be attained.

o these ends the invention consists in the improved metal fabric orstructure hereinafter described and claimed.

The invention also consists in the improved manner of joining thesections of metal fabric and further consists in the improved manneroffastening the members of a metallic structure to each other.

The invention consists still further in providing-tension .or similarbars or wires with Specification of Letters Patent. Patented lffll. 17,1914. Application filed January 26, 1909. Serial No.

clips elcctricallywelded thereto and provided with ears whereby they maybe secured to a' connecting bar or other companion member. i

In the accompanying drawings Figure 1 enlarged section through a tensionwire and clip before welding and illustrates the preferred-method ofsecuring the clip to the wire. F ig. 6 is a similar view after weld ing.Fig. 7 is a developed plan of the preferred formof cl ip.- Fig. 8illustrates the manner of forming the reinforcement for a concretecolumn.

In the various figures of the drawings, one'of the members or tensionwires of the fabricor structure is indicated at 1, while 2 indicates thedistributing wires or ion members.

It "isth'e usual practice in metal fabric used for concretereinforcen'ient to form the tension wire as a round wire or rod and thedistributing wire fiat and I will herein show themes such, but I donotlimit myself to companthe same as other suitable forms might be p ofmy invention. Also where the term "'w1re-1s employed it will beunderstood thatieither a w1re rod, bar or other similar or equivalentmember is meant.

employed without departing from the spirit 3 indicates clips which inthe preferred form are flat strips ofmetal' and electrically welded tothe surface of the tension wires 1. This electric welding of the clipsand tension'wires might be effected in any suitable way, such as forinstance, providing a point or projection 4 on the clip 3 as shown inFig. 5, passing anel'ectric current through a v the wire and .clip andpressing them together in the line of the projection, the weld whenfinished being shown in Fig. (3. The point at which the clips arepreferably welded to the tension wires is indicated at 5'. r

In the drawing Fig. 1, I'show two sections of metal fabric, theintersecting tension wires 1 and distributing wires abeing secured toeach other at their inter ec- GMSIfi of the clips 3 pass' thi'ough vHugs-18, in the connecting bars and are turned v overagainsfi'thelopposite side of'the. bars 7, thusfholdin'g. the tensionwiresl'to the bars ..7-,' the'clips of the tension wire of one section.wbein'g fastened to thc" jconnec'ting bars7. at v I .joiningsectionssaid clips having-their free "ends attached I ismadefup rigid at thefactory andcomplete being -preferably welded in itself, "the, tensionand? distributing wires their intersections.- in anytsuitable manner;
